Free-agent CB Chris Houston (Lions) is recovering from his second toe surgery and hopes to resume his NFL playing career. He expects to be medically cleared in August or September, which could jeopardize his chances of making a Week 1 roster.

Detroit Lions CB Chris Houston (toe) underwent surgery on his toe earlier this week, and it's unknown if he'll be able to make it back in time for training camp this summer. "I'm not certain, to be honest with you," head coach Jim Caldwell said. "I kind of leave those things up to our physicians. Those guys went to school for a long time to get those medical degrees and so what I do is try to focus in on what we're doing and I let them sort of navigate through it and give me an indication of it at some point in time." Houston is expected to be one of the team's starting cornerbacks this year alongside CB Darius Slay.

Detroit Lions general manager Martin Mayhew said CB Chris Houston (toe) is still dealing with the toe injury he suffered during the 2013 season. The team is still looking for the right treatment for Houston, but Mayhew did not rule out surgery.
